PIN-TONGUE.

Application filed May 5, 1921.

To all whom it may concem Be it known that I, J OHN H. HENNLssnY, a citizen of the United States, residing at rovidence, in the county of Providence and State of Rhode Island, have invented new and useful Improvements in Pin-Tongues, of which the following is a specification.

This invention. relates to certain new and useful improvements in pin tongues and pertains more particularly to the pivot means therefor.

The primary object of the invention is to provide a pin tongue pivot which is made from a piece of hollow wire, the wire being attached to the tongue with its ends extending beyond the opposite sides of the tongue and being then passed through the journal ears and expanded so as to be held against longitudinal movement relative thereto.

The invention aims to provide a simplified. improved. and ei'onomical pivot. which can be easily and quickly applied.

In the drawings:

Figure l is a side elevation of the invention;

Fig. 2 is an enlarged section on line 2-2 of Fig.1;

Fig; 3 is a detailed perspective view of a slightly modified form of the invention; and

Fig. 4. is a view of the journal ears prior to the pivot being applied thereto.

In proceeding in accordance with the present invention a front member 1 is illustrated for example. which has journal ears thereon the latter being provided with holes 3 countersunk at 4 on the outer sides of the holes. In the form of the invention shown in Fig. l the pin tongue 5 has a solid head 6 formed with an opening through which a short piece of tubular wire '7 is extended. with the ends of the wire disposed beyond the opposite sides of the head 6 as shown in Fig. 2 of the drawings and into the holes 3 of the ears 2. The ears 2 are now bent or moved toward each other until in the parallel position depicted in Fig. 2

of the drawings, following which the ends 8 of the wire 7 are expanded as shown at S to conformably engage the counter-sunk parts of the holes 3. In this way it will be seen that the pivot T is held against all movement.

Fig. 3 depicts a slightly modified form of the invention in stead of being solid as in Fig. l is formed by doublin over the flattened rear end of the tongue 0 along the line 9, the wire pivot '4 being inserted through a hole formed therefor as in the preferred form of the invention.

The advantage of having a hollow wire pivot is that a punch of usual tapering form is placed in the ends of the wire and the lat ter thus easily and qui kly expanded, enabling the wire to be most quickly and effectively secured in position, and without danger of becoming disengaged.

Having thus described my invention, what I claim as new and desire to secure by Lettors Patent is In a pin tongue pivot, a base member having a pair of ears formed with holes the outer ends of which are counter-sunk, so that the bottoms of the countersunk parts are spaced from the inner ends of the holes, a pin tongue having a head formed with a hole. andv a hollow-wire rod in the hole having its ends extended beyond opposite sides of the head and received in the holes of the ears. the ends of said hollow-wire rod being expanded to provide hollow funnel-shaped parts which onformably engage the counter-sunk outer ends of the holes of the ears, and having their outer edges flush with the respective outer side faces of the cars.

In testimony whereof I have signed my name to this spe'ification in the presence of two subscribing witnesses.
